Buchi Set boric aicid 4% Brom (4pcs) 11067888

Ready-to-use boric acid solution for Kjeldahl receiving and titration applications. The solution is 4% (w/v) boric acid, supplied with a bromocresol-type indicator, and adjusted to pH 4.65 ± 0.15 to capture and bind distilled ammonia for subsequent potentiometric or colorimetric titration. It is intended for routine nitrogen determination workflows and for laboratories performing Kjeldahl distillation with nitrogen contents ≥ 6.75 mg N absolute.

Key Features:

• Concentration: 4% (w/v) boric acid
• Indicator: bromocresol-type indicator (brom)
• pH: adjusted to 4.65 ± 0.15
• Unit volume: 5 L per canister
• Packaging: 4 canisters (4 pcs) of 5 L each

Advantages:

• Ready-to-use formulation eliminates time-consuming preparation and ensures consistent concentration and indicator ratio
• pH-adjusted solution (4.65 ± 0.15) provides reproducible conditions for accurate potentiometric or colorimetric titration
• Integrated bromocresol indicator enables clear visual or automated endpoint detection for Kjeldahl ammonia capture
